DEVICE FOR CLEANING WELLS.

T o all whom it may concern:

Be it known that I, FRANK A. MONROE, a citizen of the United States, andresident of Bemus Point, in the county of Chautauqua and State of NewYork, have invented a new and useful Improvement in Devices -lforCleaning Oil-l/Vells, of which the following, taken in connection withthe accompanying drawings, is a full, clear, and exact description.

This invention is an improvement upon the oil well cleaning mechanismshown in Letters Patent Number 884,675, and relates to improvements inthe means for removing` paratlin, the thickened product of petroleum, orother deleterious substances from the oil bearing portion of the well.

The object of the present improvement is to provide means for increasingthe eliiciency of the steam producing mechanism so as to largelyincrease the production of steam and render the action more convenientand sure of operation, and the novelty lies in the combination andarrangement ot' the parts as shown in this specification and drawingsand pointed out in the claims.

In the drawings, Figure l is a vertical sectional view of the upperportion ot' the improved cleaner; and Fig. 2 is a similar view of thelower portion, the metal billets being shown only partly in section inorder t0 show the spiral enlargement for the direction and control ofthe steam. Fig. 3 is a side elevation of the upper end of the cleanershowing the inlet and air valves. Fig. l is a vertical sectional view ofthe nozzle at the lower end of the reservoir; and Fig. 5 is a sideelevation of the screw valve or plug which is insertible within saidnozzle. Fig. 6 is a sectional view at line X X in Fig. 8. Fig. 7 is aside elevation and end view of the wrench for opening valve plug. Fig. 8is a side elevation of the nozzle with the plug inserted and the lowertubular portion in section, and a side elevation of the metal billetswith the wrench extending up through the same to turn the valve plug.

Similar numerals refer to corresponding parts in the several views.

The numeral 10 indicates the tubular casting at the lower end of thetubular reservoir which unites parts 11 and 12 of the tubular casing.Part 10 is formed with a central flange 13, the outer sides of part 10being formed above and below flange 13 so that parts 11 and l2 of thetubular casing may Specification of Letters Patent.

be attached on to the same in any suitable manner, it only beingnecessary to form a tight joint. A screw plug 14 is provided for theupper end of part 11 of the casing having a suitable bail l5 therein forsupporting line 16. Plug 14 also has an inlet valve 17 and an air valve18 thereon.

The tubular connecting casting 10 is formed with a. crosswise partition19 into the center of which a nozzle portion 2O is screwed, which nozzlehas a raised portion 21 extending up into the reservoir 22. Part 21 hasa small opening 23 extending down therethrough to allow of the slowegress of the water from reservoir 22. Nozzle 2O is tubular in form, andthe opening 23 is enlarged before it enters the tubular cavity 2l:within the lower portion. The lower end of cavity 24 is closed by meansof a screw plug 25 which bears a conical pointed extension 26 on itsupper side which conical point fits within a valve seat at the lower endof opening 23 thereby forming, as it were, a needle valve at the lowerend of said opening which spreads or distributes the water in alldirections around said conical point and within cavity 24 when plug 25is withdrawn suficiently from the valve seat to allow egress of thewater.

The outer side of the tubular lower end of part 20 has a shoulder 27 cutthereon and is correspondingly less in size. The outer side of tube 2Ol'rom shoulder 27 downward being threaded to receive an outer tubularportion 28 which extends down below part 20 and plug 25. The lower endof plug 25 has an outwardly beveled flange 29 to distribute the water onto the inner side of tube 28, so that it will fall about midway betweenthe outer and inner sides on the upper end of billet 30, as shown inFig. 1. Tubular nozzle portion 20 has a circular cut 31 around its outerside above the plug 25 when inserted therein, and openings 32 from innercavity 211 to cut 3l, vertical grooves being cut from each hole 32 tothe lower end of part 20, as shown in Figs. 1 and 8.

A hexagonal extension 33 is provided on the lower end of plug 25 toreceive the upper end of a wrench 34, which wrench is of sutlicientlength to extend up through the billets 30 and embrace part 33 foropening valve 26. Y

Billets 30 are made with a tubular opening 35 extending therethrough,except in the lower billet, wherein near its lower end I 37 andsuperlieating the steam.

Lower part 12 of the casing has a series 0f minute openings 38 at spacedintervals down the length of the same. The lower end of the lower pait12 is closed with a screw plug 39 having a bale 40 to turn the plug, aswell as to support the cleaner at the bottom of the well.

In order to stop the billet 30 at a spaced distance from the lower endof tube 28 within casing 12, a number of short screws 41 are inserted incasing 12, so that when it is desired to enter the billets 30 intotubular casing 12 after reservoir 22 has been filled, the cleaner isturned bottom side up and all but the last billet inserted. lThe screwsor stops 41 will hold the hot billets from approaching too near to part28. rfhe plug 25 is then turned sufficiently to open needle valve 26 byinserting wrench 24 through the hot billets, the tubular opening 35forming a guide for the wrench to the hexagonal extension 33 on plug 25,as shown in Fig. 8, after which the last or plugged billet is insertedand plug 39 is screwed to place. The cleaner is then turned right end upand iminediately inserted in the well; and it is obvious that the waterwill pass down through the nozzle and over the hot billets and they willimmediately begin to steam, the steam passing out of the minute openings38 into the well.

In order that the water in reservoir 32 may be forced down through thenozzle 21, a tube 42 is inserted in partition 19 and extends up throughthe water to a close proximity to the under side of plug 14, so that thesteam will pass up through the same, and into the space above the waterwithin the reservoir, thereby heating the water and exerting pressureupon the saine.

I claim as new:

1. In a device for cleaning oil wells, a tubular casing, a removablemetal billet in said casing having a spiral projection on its outer sideto detain fluid thereon, a reser Voir for fiuid in said casing, andmeans for 1 permitting the passage of said fluid on to said billet.

2. In a device for cleaning oil wells, a tubular casing composed of twoparts, a metal connection for said parts having a partition therein toform a reservoir for liquid in the upper part of said casing, and meansfor the passage of the liquid through said partition.

3. In a device for cleaning oil wells, a tubular casing composed of twoparts, a connective casting for said parts having a partition therein toform a reservoir of the upper part of the casing, a tubular nozzleinserted through said partition, and a screw valve on the under side ofsaid nozzle.

4. In a device for cleaning oil wells, a tubular casing composed of twoparts, a con.- nective casting for said parts having a partition thereinto forni a reservoir of the upper part of the casing, a tubularextension on the under side of said partition having a small openingthrough said partition, a

screw valve in the lower end of said t-ubiilar extension having a valveseat in the lower end of said small opening, said tubular extensionhaving openings through the sides thereof, and a tubular shield tocontrol the liquid from said openings.

5. In a device for cleaning oil wells, a tubular casing composed of twoparts, a connective casting for said parts having a partit-ion thereinto form a reservoir of the upper part, a tubular nozzle extendingthrough said partition and having a small opening therein, a screw valvein the lower end of said tubular nozzle having a valve seat at the lowerend of said opening in said nozzle, said tubular nozzle having openingsthrough the sides thereof, a tubular shield to guide the liquid fromsaid openings, said screw valve having a flange on its lower end, and acentral squared nut, substantially as and for the purpose specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
